USB-to-Serial & USB HUB Chips Solutions | WCH Alternatives
With the rapid development of industrial automation, consumer electronics, medical devices, communication equipment, and the Internet of Things (IoT) industry, the USB interface has become an indispensable data transmission and connectivity standard in modern electronic products. Whether it is USB-to-serial communication or USB hub port expansion, related interface chips play a critical role in device interconnection, data exchange, and system control, with continuously growing market demand.At the same time, driven by global supply chain adjustments, rising prices of imported chips, and fluctuations in delivery cycles, an increasing number of companies are turning their attention to domestic USB interface chip solutions. Compared with imported products, domestic solutions not only effectively reduce procurement costs, but also offer advantages such as stable supply, controllable lead times, and localized technical support. This article will focus on USB-to-serial chips and USB hub controller chips, and introduce the application advantages and selection directions of their alternative solutions.(Contact us for a quote) What is a USB-to-Serial Chip?A USB-to-Serial chip (USB to UART Bridge IC) is an interface device that enables conversion between USB interfaces and serial communication protocols. Its core function is to convert USB signals from a computer into traditional serial communication signals (such as UART or TTL levels), thereby enabling stable communication between modern USB-based devices and embedded systems. This type of chip is widely used in microcontroller development boards, industrial control equipment, debugging tools, and various embedded systems. 1. Working Principle of USB-to-Serial ChipsThe operation of a USB-to-Serial chip is essentially a process of “protocol conversion + data buffering + level adaptation.” When a computer sends data via the USB interface, the internal controller of the chip first parses the USB protocol packets and converts them into serial communication data (UART format), which is then output through TX/RX pins to the target device.In the reverse direction, UART data transmitted from the serial device is repackaged into USB data packets by the chip and sent back to the computer via the USB interface, enabling bidirectional communication. 2. USB and UART Protocol ConversionThe USB protocol is a complex host-controlled high-speed communication protocol, whereas UART is a simple asynchronous serial communication method. The key function of a USB-to-Serial chip is to seamlessly bridge these two fundamentally different communication mechanisms:l USB side: responsible for device enumeration, data packet encapsulation, and high-speed communication with the PC hostl UART side: responsible for simple, low-speed, point-to-point communication with MCUs or peripheral devicesThrough an internal protocol conversion engine, the chip converts USB data streams into standard UART frame formats (start bit, data bits, parity bit, stop bit), enabling cross-protocol communication. 3. Enabling Communication Between PC and MCUIn embedded development, USB-to-Serial chips serve as the most common communication bridge between PCs and MCUs (microcontrollers). Developers can use serial terminal tools on a computer to directly interact with MCUs, enabling:l Firmware downloading and upgradingl Real-time data monitoringl Command transmission and response feedbackl System status debuggingThis communication method is simple, stable, and cost-effective, making it an essential tool in engineering development.(Contact us for a quote) USB-to-Single-Serial Port Chip SolutionThe USB-to-single-serial port chip solution integrates a USB interface and a single UART channel into one chip, enabling an efficient and compact communication architecture.

BAT54S Diode: Pinout, Test Circuit and Applications
What is BAT54S?The BAT54S is a dual planar Schottky barrier diode for high-speed switching and low-forward voltage applications. It features integrated guard ring protection technology. Encapsulated in a SOT-23 (TO-236AB) surface-mounted package, the BAT54S is widely used in portable electronics. BAT54S Working PrincipleThe operating principle of the BAT54S is based on the physical characteristics of a metal-semiconductor junction (Schottky barrier). Since it does not have the minority carrier storage effect found in traditional PN junction diodes, it offers an ultra-low forward voltage drop of only 0.3V–0.4V and an extremely fast reverse recovery time in the nanosecond (ns) range.In practical circuits, when the input voltage exceeds the supply voltage or drops below the ground level, the corresponding diode instantly turns on in forward conduction mode, quickly diverting abnormal overvoltage or negative spike pulses to the power rail (VCC) or ground (GND).(Contact us for a quote) BAT54S SpecificationsNexperia BAT54S,215 technical specifications is below.ParameterValuePart NumberBAT54S,215Diode TypeSchottkyDescriptionDIODE ARRAY SCHOTTKY 30V SOT23Lead Free Status / RoHS StatusLead free / RoHS CompliantDiode Configuration1 Pair Series ConnectionSeriesAutomotive, AEC-Q101Operating Temperature - Junction150°C (Max)Reverse Recovery Time (trr)5nsVoltage - DC Reverse (Vr) (Max)30VVoltage - Forward (Vf) (Max) @ If800mV @ 100mAMounting TypeSurface MountCurrent - Reverse Leakage @ Vr2µA @ 25VCurrent - Average Rectified (Io) (per Diode)200mA (DC)Current Rating500mAPeak Reflow Temperature (Cel)260Time@Peak Reflow Temperature-Max (s)30PackageTO-236-3, SOT-23-3Base Product NumberBAT54S BAT54S Pin DescriptionPin 1 — A1: Anode terminal of diode 1.Pin 2 — K2: Cathode terminal of diode 2.Pin 3 — K1 / A2: Shared terminal functioning as the cathode of diode 1 and the anode of diode 2. BAT54S Test CircuitReverse recovery time test circuit and waveforms This figure shows the standard test circuit and waveform used to measure the reverse recovery time (trr) of the BAT54S.In the test circuit on the left, the device under test (D.U.T.) is first driven with a forward current IF by a DC current source. Then, a fast reverse voltage pulse is applied by a pulse generator with an internal resistance of RS = 50Ω. Since Schottky diodes use a metal-semiconductor junction and do not have the minority carrier storage effect of standard PN junction diodes, only a very small reverse current spike appears when the signal quickly switches to reverse bias VR. As shown in the output waveform on the right, the reverse current rapidly decays to the specified threshold current IR = 1mA.(Contact us for a quote) BAT54S Featuresl Dual Schottky diodes integrated in one compact package.l Ultra-small SOT-23 SMD package for easy PCB assembly.l Nanosecond-level fast switching performance.l Low forward voltage drop of about 0.35V–0.4V.l Supports up to 30V reverse voltage.l Maximum continuous forward current of 200mA.l Surge current capability up to 600mA.l Extremely low charge storage effect.l Excellent overvoltage and ESD clamping performance.l Available in AEC-Q101 automotive-grade versions.l RoHS compliant and lead-free design. BAT54S Applications1. Ultra High-Speed SwitchingThanks to its nanosecond-level switching speed and low forward voltage drop, the BAT54S is widely used in high-frequency and fast-response switching circuits. It is suitable for RF circuits, signal routing, pulse detection, and high-speed digital communication systems. 2. Line TerminationThe BAT54S can be used in line termination circuits to suppress signal reflections and improve signal integrity in high-speed data transmission systems. It is commonly applied in communication interfaces, data buses, and embedded electronic systems. 3. Voltage ClampingThe BAT54S is ideal for protecting sensitive I/O ports and low-voltage components from transient voltage spikes or electrostatic discharge (ESD). It is frequently used in USB ports, microcontroller interfaces, sensor inputs, and portable electronic devices. 4. Reverse Polarity ProtectionThe diode provides efficient reverse polarity protection with minimal power loss. It helps prevent damage caused by incorrect power supply connections in battery-powered products, industrial controllers, and consumer electronics.(Contact us for a quote) BAT54S EquivalentsIf you are looking for compatible alternatives for the BAT54S, the following models are commonly used in similar Schottky switching, clamping, and protection circuits:l BAT54l BAT54Al BAT54Cl BAT54SDWl BAT54S-7-Fl BAT54ST-7-Fl BAT54T1G BAT54 vs. BAT54S vs. BAT54A vs. BAT54CThese four models typically use a SOT-23-3 package, and their main difference lies in the internal diode pin configurations.

Similarly, when a negative spike below about -0.3V appears, the lower diode conducts and clamps it to ground. BAT54S PackageHere is the BAT54S package outline.
